$makenek clean doesn't delete the unpacked versions of parRSB and gslib. When parRSB, for example, is updated, the user needs to manually delete theNek5000/3rd_party/parRSB/parRSB directory for the new version to be downloaded and installed. Theinstall script only checks for the existence of the tool subdirectory when deciding if it needs to download a new tarball, not whether it is the correct version. We could tag the subdirectory with the version number to make sure it's always consistent with the version of Nek. Something like:

#!/bin/bashset -eVER=0.9.2if [ "$1" == "clean" ]; then  rm -rf parRSB_v$VER/build lib include 2>/dev/null  exit 0fiif [ -f ./lib/libparRSB.a ]; then  exit 0fiif [ ! -d ./parRSB_v$VER ]; then  rm -rf ./parRSB* 2>/dev/null #delete any version that might already exist  wget --no-check-certificate -O v$VER.tar.gz https://github.com/Nek5000/parRSB/archive/v$VER.tar.gz  mkdir parRSB_v$VER  tar -zxvf v$VER.tar.gz -C ./parRSB_v$VER --strip-components=1ficd parRSB_v$VERset -xmake lib install $PARRSB_OPTset +x
